A method for the fronto-parallel recovery of paragraphs of text under full perspective transformation is presented. The horizontal vanishing point of the text plane is found using an extension of 2D projection profiles. This allows the accurate segmentation of the lines of text. Analysis of the lines will then reveal the style of justification of the paragraph, and provide an estimate of the ve...

In heart failure localized interlober pleural effusion is rare but well-known finding. But there is not enough case reports in the literature. This radiological finding seems like a mass and undergoes resolution quickly, It is also known as vanishing tumor, pseudotumor or phantom tumor. It is difficult to estimate the incidence due to the small number of reported cases. Determination of the mas...

We report a case of vanishing tumor considered as inflammatory pseudotumor (IPT) found in the liver after living donor liver transplantation (LDLT) from a hepatitis B virus surface antigen-positive donor. The radiological findings were similar to those of hepatocellular carcinoma (HCC). However, the tumor disappeared completely within several months and was suggested to have been an IPT. IPT is...

background: congenital adrenal hyperplasia (cah) and vanishing testes are uncommon diseases that can result from hormonal and mechanical factors. classic cah is determined by ambiguous genitalia and increase in amount of 17-hydroxyprogesterone. simultaneous occurrence of cah and vanishing testes is a rare condition. case: a 22-year-old boy, known case of cah who was diagnosed as female pseudohe...

We consider the problem of matching perspective views of coplanar structures composed of line segments. Both model-to-image and image-to-image correspondence matching are given a consistent treatment. These matching scenarios generally require discovery of an eight parameter projective mapping. However, when the horizon line of the object plane can be found in the image, done here using vanishi...

The florentine Tommaso Cassai (1401-c.1427) 1 better known as Masaccio, has been hailed as the first great painter of the Italian Renaissance and his fresco Trinity (c.1425, Santa Maria Novella, Florence) as the first work of Western art that used full perspective. It appears that the author was inspired and actually helped by his friend Filippo Brunelleschi (1377-1446), the celebrated architec...

The theory of local homology modules was initiated by Matlis in 1974. It is a dual version of the theory of local cohomology modules. Mohammadi and Divaani-Aazar (2012) studied the connection between local homology and Gorenstein flat modules by using Gorenstein flat resolutions. In this paper, we introduce generalized local homology modules for complexes and we give several ways for computing ...

In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.

In this paper we introduce two different representation approaches and propose two techniques to estimate the position of vanishing points in an image, one based on a probabilistic strategy and the other focused on a deterministic analysis. Unlike most of the methods so far developed, which exploit the Gaussian sphere, the new techniques operate in the (ρ, θ) polar parameter space and in the (x...

We present a novel perception-driven approach to low-cost tele-presence systems, to support immersive experience in continuity between projected video and conferencing room. We use geometry and spectral correction to impart for perceptual continuity to the whole scene. The geometric correction comes from a learning-based approach to identifying horizontal and vertical surfaces. Our method redra...
